I stopped down at BMW earlier this afternoon and no luck yet. They said that Matson has no more than 4 days to release the car. Today was day three according to the manifest they pulled up. So if they were able to get it tonight maybe Sunday...

I experienced that last wait from Matson to the dealer as the worst wait of all.. My car arrived on April 4 (Wednesday) in Honolulu with the same ship, Matson would not release the car until April 9 the earliest, which indeed happened. I finally would take delivery on Tuesday, a day after it got at the dealership. I'm kind of thinking it might be similar in your situation
